Introduction to JavaScript

?? WHAT IS JAVASCRIPT?

JavaScript is a dynamic programming language that's used for web development, in web applications, for game development, and lots more JavaScript is a “scripting language”. JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive.

?? USES OF JAVASCRIPT

JavaScript is also used beyond the Web in software, servers, and embedded hardware controls. Here are some basic things JavaScript is used for:

? Back-end web development

JavaScript is MOSTLY used on the front end of things, but it’s a versatile enough scripting language to be used on back-end infrastructure, too.

? Developing mobile applications

JavaScript isn’t just for websites…it’s used to create those apps you have on your phone and tablet as well

? Adding interactivity to websites

JavaScript allows users to interact with web pages. There are almost no limits to the things you can do with JavaScript on a web page –

? Creating web browser-based games

Ever played a game directly from your web browser? JavaScript probably helped make that happen

?? WHY JAVASCRIPT IS POPULAR?

It isn’t a single item on this list but the combination of all of these things that makes JavaScript so popular. No other programming language offers everything on this list.

• Something for everyone: JavaScript implements multiple paradigms, procedural, oop, and functional. This mix gives everyone some of what they want.
• Runs on the web: JavaScript is the primary language of a little bit of tech called the world wide web. It is practically speaking the only language that runs in the browser.
• Performance: JavaScript is not the fastest language but it is fast. This combined with scalability and ease of use makes JavaScript ideal for most tasks.
• Easy to start: Getting a web server up and running in Node.js is simple and fast. It requires little overhead and runs on Unix, Windows, and Macs.

?? BENEFITS OF JAVASCRIPT

Let us now see some of the benefits of JavaScript that make it so a functional and convenient programming language.

? Amazing Libraries/Frameworks

There is a record of great frameworks built around JavaScript which boast ready use ready-to-use codes. All such codes are clean to recognize as well as debug. Moreover, depending on the framework in the query, you may get the right of entry to plenty more features to grow your productivity ten folds.

? JavaScript Keeps Evolving

If you have been wondering if JavaScript is dying then it is not! Stuff like video games, and automatic controllers, all have included JavaScript in their making. JS even reveals a few devotees within the subject of robotics.

? Platform Independence

JavaScript is a platform-independent language. Any JavaScript-active browser can recognize and interpret JavaScript code. Any JavaScript code is completed on specific forms of hardware a JavaScript program is written for.

? Runs on the Client-Side

JavaScript code snippets don’t require to be dispatched to the server thing for being processed. This saves the burden on the server element. The JavaScript code in an internet site gets processed through the use of the sources at the customer’s machine.

JavaScript was initially created as a browser-only language, but it is now used in many other environments as well.

Today, JavaScript has a unique position as the most widely-adopted browser language, fully integrated with HTML/CSS.
